If you remember a few weeks ago I was attempting to get responses to 'mixing decoders" where I was asking about mixing NCE with Digitrax in N scale. Well I have the Digitrax replacement for the first one I think I messed up but they replaced, and even though they run better now they still dont run well together. One unit runs great while the other is very noisy and seems as if the drive train is binding up. The sound it makes reminds me of the old spring drive units. I pulled it complettely apart and lubed it but no luck. I cannot find anything wrong?
I took the noisy unit apart and cleaned it. I inspected with a magnifier but could not find anything. I have heard froma few sources that it sounds like a cracked gear or axle but I could not find. So I re-lubed it and installed a matching Digitrax decoder and speed matched them again. I set the BEMF on 15 and they seem to run fairky well but could be better. Its too bad, I have a few Atlas locos that after speed matching run great.
Any suggestions on a fix or could someone inform me as to how to get a replacement assembly?
